Having the same drag and drop MIDI issues as mentioned in the other reviews. Did much research and can't find a workaround so the MIDI record function seems worthless. Using windows 10 64-bit and reaper. Also seems unable to play gm files from producer loops. Tried moving the notes up and down an octave in the MIDI editor and that did not fix the issue. The sound quality is good, but these MIDI issues are aggravating.
Air support asked to redeem one at the time, tried both ways, none seem to work.
Tried again, one code at a time, this time the codes were fine but an error comes up Payment Authorisation failed then I go back and then when I go back and input the codes again the Code not valid error comes up.
